I'd love to see the thread on "internal buses can't be sub-bused," but the link in your post is broken. Can you direct me?

The target's probably been deleted.

The error message reflects a limitation in HDL.  What you need to do is to create two different internal buses that are the widths you need.  For example, if you need the 16-bit word in one place and the low byte in another you can write
    And16(a=foo, b=bar, out=and_word, out[0..7]=and_low_byte);
